Description
A new method has recently been developed to obtain the Fried's parameter from observations of granulation outside the disk center, based on the different degradation suffered by the images on the directions parallel and perpendicular to the solar limb, due to the geometrical foreshortening. This procedure has been applied to CCD images obtained at the Swedish Solar Tower of the Observatorio del Roque de los Muchachos, with satisfactory results which are presented and discussed.

    Workshop summary: Kaons@CERN 2023

    Kaon physics is at a turning point - while the rare-kaon experiments NA62 and KOTO are in full swing, the end of their lifetime is approaching and the future experimental landscape needs to be defined. With HIKE, KOTO-II and LHCb-Phase-II on the table and under scrutiny, it is a very good moment in time to take stock and contemplate about the

    Finding Water Worlds with Transit Timing Variations

    Models predict that planets with water-rich compositions may be common around low-mass stars, but definitive evidence for the existence of water worlds has remained elusive. Precise mass and radius measurements for small planets allow us to identify candidate water worlds that have bulk densities too low to be consistent with a rocky composition

    Nodal Precession of a Hot Jupiter Transiting the Edge of a Late A-Type Star TOI-1518

    TOI-1518b, a hot Jupiter around a late A-type star, is one of the few planetary systems that transit the edge of the stellar surface (the impact parameter b~0.9) among hot Jupiters around hot stars (Cabot et al. 2021). The host star's high rotation speed (Vsini s~85 km s -1) and the planet's nearly polar orbit (λ~120 deg) may cause a nodal
